Abstract

Research on the use of Chorella sp. on reducing of Zn concentrations was conducted in order to know Zn concentration which is maximally absorbed by Chorella sp. In the preliminary experiment, there was the range of Zn concentration that caused the highest population growth of Chorella sp. was 0.1 – 0.4 ppm. In the main experiment, it was divided into five concentrations and one control with three replications. Each of concentrations was treated on Chorella sp. culture with the first Zn concentration (0.0042 ppm) in the medium culture. Those concentrations were 0.05 ppm, 0.15 ppm, 0.35 ppm, 0.45 ppm. All of the concentrations were given on the day of 5. The density of cells which was used for each flask was 100,000 cells/ml. The fertilizers used for each flask were : ZA, Urea, TSP, FeCl3, EDTA. The result showed that there was an interaction between the population growth of Chorella sp. and the reducing of Zn concentration. The highest population growth of Chorella sp. was found in the treatment of 0.15 ppm Zn concentration.

Abstract

Biomonitoring methods for water quality, such as coli form content, diversity and evenness indices of macrobenthic invertebrates and plankton which are recently used, actually have some weaknesses. Escherichia coli only indicated pollution caused by faecal coli; macrobenthic invertebrates have not ability to live in all substratum, whereas the population of phytoplankton are affected by current as they are floating in the surface water. Therefore, the method which are more effective have to be developed. Epipelic diatoms have potential characteristics as bioindicator of water quality because the have ability to accumulate physic-chemical component of aquatic ecosystem and respond it immediately. This research is conducted in order to find out a new alternative of biomonitoring method ( species indices of diatoms ) which are more significant, effective and efficient by determine water quality map absed on diatoms and determines the species which responsible to the grouping. Sediments samples were taken from 7 rivers in the Northern Coast of Central Java (called Pantura): Karanggeneng-Rembang, Juana-Pati, Banjir Kanal Timur-Semarang, Banjir Kanal Barat-Semarang, Banger-Pekalongan, Pekalonghan-Pekalongan, and Gung-Tegal. Temperature, dissolved oxygen, salinity, pH and turbidity were measure in-situ.  Analysis of water and sediment samples include total nitrogen, total phosphorus,silica, heavy metals of Cu, Cr, and Cd. Extraction, preparation and identification of diatoms followed Wetzel & Likens (1991) and Round (1993). The`data were then analysed using Primer package progamme version 4.0 which is produced by Plymouth Marine Laboratory, United Kingdom (Carr, 1997). The Multi Dimentional Scaling (MDS) ordination was done to make grouping and was followed by SIMPER analysis to determine responsible species (Clarke & Warwick, 1994). Based on diatom community, 7 river Pantura could be divided into 3 groups: Group I, consisted of Gung and Pekalongan Rivers, Group II of Banjir Kanal Timur, Barat and Banger Rivers and Group III Karenggeneng and Juana Rivers. Synedra ulna was responsibled for those grouping and are therefore could be promoted as bioindicator of water quality in the Indonesian river. Research still should be developed, especially for diatoms in the bottom layer of sediment samples to reconstruct ecological condition in the past and to predict the condition in the future.

Abstract

The natural mangrove ecosystems along the Northern Coast of Central Java were very limited in extent, even had replanted almost twenty years ago. Naturally, the upper layer of sediment are the latest deposition (superposition). Environmental condition recently are recorded in the top sediment layer, and can be used to reconstruct past condition  (the present is the key to the past). The potential use of diatoms to reconstruct palaeoecology is well established. Diatoms are microscopic algae that form siliceous frustules which make them well preserved in sediment. Diatoms and their assemblages are very useful as integrated indicators of environmental changes because their distribution is closely linked to water quality parameters as well as their affinities to several physical habitats. This research was conducted in order to determine the changes of mangrove ecosystem in the Northern Coast of Central Java based on diatom stratigraphy. Sediment samples from mangrove sites were taken from Pekalongan, Brebes, Semarang, Demak and Rembang. Diatom analysis, consist of digestion, preparation, and identification. The diatom stratigraphy was performed by Software of  C2 1.5.1. Stratigraphycally, the mangrove ecosystems along the Northern Coast of Central Java were previously more influenced by freshwater rather than the marine sources which dominate today.

Abstract

Research on Spirulina sp. has been development since it was found to have a high economic value and as healthful as human traditional food such as the fishes. Therefore, the factors that influence the culturing of this algae should be maintained properly to obtain a high quality of the product. The research was done to determine the interaction of salinity and the dosage of the urea fertilizer on the population growth of Spirulina sp. factorial design with the combination treatment of four salinities (12,5 ppt, 15 ppt, 17,5 ppt, 20 ppt) and three dosage of urea fertilizer (80 ppm, 100 ppm, 120 ppm), are applied with 3 replications. The result indicated that the highest Spirulina sp. population is 321000 unit/ml, wet weight is 3,349 gr/l and dry weight is 1,315 gr/l which was found on the 20 ppt salinity and 120 ppm of urea fertilizer dosage.
